Australia's richest person, Gina Rinehart, is looking to invest up to half a billion dollars to produce infant milk formula for China. The Hope Dairies project is looking to establish Australia's biggest dairy operation, by acquiring 5,000 hectares of farmland in Queensland's South Burnett and building a processing plant in the nearby Mary Valley. Hope Dairies is controlled by Ms Reinhart's Hancock Prospecting Ltd and is a move to diversify beyond her huge mining interests. Project spokesman Jason Morrison says the plan would see production start in late 2016, "It'll be a big thing - not just because it will revitalise the industry but it'll inject a bit of hope into it as well and an enormous amount of export revenue for Australia".
